@igorlord it appears you're describing a case when policy precludes migrating with the SPA, even though it is likely to work from a technical perspective.

In this case, I believe you need to send a stateless reset to any clients that change IPs to ones which are not supported.  You'll want to do that anyway, but that does cost a round trip.

The design change would be to add a disable migration feature for every server IP, but I'm not sure that's warranted to save a round trip in this specific case.
